HUGH ID. BROWN, or I'II-IACA, NEW YORK.

ELEVATING-TRUCK.

Application filed February 5, 1916.

To all whom it may concern:

Be it known that I, HUGH D. BROWN, a citizen of the United States of America, re-

' siding at Ithaca, in the county of Tompkins and State of New York, have invented certain new and useful Improvements in Elevating-Trucks, of which the following is a specification.

This invention relates to new and useful improvements in elevating trucks.

The present device in the form of a transfer truck is primarily designed for handling baggage andexpress and transferring the same to and from railway cars, the floors of Which are often positionedat considerable and different heights from the station platforms adjacent thereto, the invention affording a ready means for making such transfers quicker and easier.

A further object of the invention is the provision of a transfer truck in which the receiving platform may be positioned in close proximity to the floor for loading and is capable of then being readily elevated to substantially the height of the receiving platform whereby the load may be readily transferred, it being understood that the device is also operable in a. substantially opposite manner for the lowering of goods from one point to another.

A still further object of the invention is to provide a baggage truck that may be manually moved and that iseasy and inexpensive to manufacture and by means of which one man may easily load and unload large quantities of goods, such as baggage of great weight. v I

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

Fig. 2 is a top plan view thereof with the platform broken away. Fig. 3 is an end elevation of the same. Fig. 41 is a transverse sectional view taken through the device with elements removed.

member, and Figs. 6 and 7 are detail Views of pulley members employed with the device.

Referring more in detail to the drawings, it will be seen that the device broadly consists of a wheel truck frame 10 having a receiving platform 11 vertically shiftably mounted thereon and manually operable for ralsing and lowering by the mechanism hereinafter described. The frame 10 is formed of parallel channel bars or rails 12 having reinforcing blocks 13 arranged therein and mounted upon front and rear bolsters 14: provided with supporting wheels 15 in substantially the usual manner, a handle or tongue 16 being arranged for manually propelling the truck. The rails 10 terminate at their forward and rear ends in upright posts 17, the connecting beam 18 being arranged between the upper ends of each pair of posts positioned at opposite ends of the frame 10. The goods receiving platform 11 is positioned above the rails 12 and adapted to rest thereon when in its lowermost arrangement and is provided with anti friction rollers 19 ournaled in its opposite ends and adapted to ride upon the posts 17 during any longitudinal shifting of the platform during the operation thereof. Corner stakes 20 are mounted upright upon the platform 11 at the opposite ends of the rollers 19 and assist in positioning and retaining the goods upon the platform.

An operating shaft 21 is mounted transversely beneath the platform by means of journaling brackets 22 carried by parallel stringers 23 upon which the said platform is secured, the opposite ends 24 of the said stringers projecting forwardly and rearwardly of the truck frame 10 and outwardly of the posts 17 thereof.

Double winding drums 25 are secured to the operating shaft 21, a removable crank 26 being arranged for fitting the opposite squared ends 27 of the said shaft for operatively turning the same. A ratchet wheel 28 18 provided at each opposite end of the shaft 21 and has a cooperating springpressed pawl 29 normally in contact therewvith but adapted to be retained out of enthe side rails 12, with the stringers 23 of the platform lying outwardly of the said frame rails.

Oppositely arranged pulleys 32 having their upper portions covered as best illustrated in Fig. '3 of the drawings, are arranged upon the outer sides of the beam 18,

while similar pulleys 33 positioned with cables 36 are provided four in number, two

being arranged at each end portion of the device and each having a corresponding end secured adjacent an end of each beam 18 as at the pins 37. The cables 36 pass over the anchoring pins 37 downwardly over the pulleys 33, thence upwardly over the pulleys 32, thence downwardly over the pulleys 35 and are carried forwardly beneath the platform 11 and are all wound in the same direction over the pulleys 25, the adjacent ends of the cables 36 being secured to the said pulleys.

From this detailed description of the device, it will be understood that when the platform 11 rests upon the rails 12 in its lowermost position, the stringers 23 will lie outwardly of the rails 12 and the platform being In close proximity to the floor or foundation 38 upon which the truck is mounted, trunks, baggage or any other articles may be readily placed upon the said platform. The crank 26 which may be hung upon the hook 39 when not in use may be applied to a convenient end 27 of the shaft 21 and operatively turned for revolving the said shaft and the winding drums 25 thereon, thus winding up the cables 36 upon the said drums, thus elevating the platform 11. The pawls 29 thus freely ride over the wheel 28 and retain the platform at the desired adjusted height, so that the articles may be readily removed therefrom to an elevated position. When it is desired to lower the platform 11, the handles 40 of the pawls 29 may be grasped and lowered, thus elevating the pawls from the. wheels 28 and the stops 30 will automatically drop into position for retaining the pawls released, it being understood that the crank 26 may be employed for easing the platform in its descent to the desired distance and that one of the pawls 29 may then be engaged with the wheel 28.

It is known that elevating trucks have been heretofore employed but the present truck is especially adapted for manual propulsion in transferring baggage and articles at railway stations or similar points by which arrangement one man may readily transfer by moving, elevating and lowering a great weight of baggage such as a ton or the full capacity of the truck rendering the device a time-saver where such is a great object to be attained.

\Vhile the form of the invention herein shown and described is what is believed to be the preferred embodiment thereof, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

hat I claim as new is 1. An elevating baggage truck comprising a channel iron frame having parallel side bars provided with oppositely arranged central depressions, integral upright posts at the opposite ends of the said bars, crossbeams connecting the upper ends of the said posts, supporting wheels beneath the said frame, a platform shiftably arranged above the said bars and between the said posts, upright corner stakes carried by the said platform, anti-friction rollers journaled in the opposite ends of the said platform between each pair of said stakes, and arranged adj acent the said end posts, opposite stringers longitudinally arranged beneath the said platform and positioned outwardly of the said rollers, the opposite ends of the said stringers projecting beyond the said frame posts, an operating shaft journaled transversely beneath the said stringers in alinement with the said depressed portions of the bars, flexible hoisting means operatively connected to the said shaft and posts and means for revolving the said shaft.
